Brusters Free Doggy Sundaes

I love Bruster's Ice Cream! There's one up the road from my house, and I always take my nieces there when we have a sleepover. I just found out they give out free doggy sundaes to each canine visitor that stops by their store! Now, I also know that real ice cream is not supposed to be good for dogs, I've heard they cannot digest it properly...so I'm curious as to what they use in the doggy sundae. Maybe it's a real ice cream for the dog's Mom to enjoy!! I guess I'll have to take Snoopy with me next time and find out!
